Letters Patent No. 105,697,-date1l July 26, 1870.

The Schedule r ferred to in these Letters Patent and making pm of the same To all whom it may concern:

Be it; known that I, JEROME KIDDER, M. 1)., oi the city, county, and State of New York, have invented a new and useful Compound Switch for Batteries, of which the following is a. full, clear, and exact description, reference being bad to the accompanying drawing forming part of this specification, and in whicl Figures 1 and 2 represent opposite or upper and under face views of a. compound battery-switch, constructed in accordance with my invention, and

Figure 3, a transrerse section of the same.

Figure disa diagram, in illustration of the conheel-ion of the switch with the cups of the batteiy.

Similar letters of reference indicate corresponding parts.

My invention, which may be applied to batteries for medical use, and for various olher purposes, consists in acompound switch, or combination of two switches," insulated the one. from the other, and made capable of independent rotation around one and the same center said switches being independently counecied with the wires or opposite ends of the wire by which the circuit is completed, and be ng arranged to travel over a oirouibbreaker and closer formed of insulated conductors, that connect each with a separate cup or cups of the battery.

By the (wustruction and operation of said compound switch, as hcreinaficr described, any number of cups may ho broughtinto connection, or the polarity be reversed, at pleasure; also, by it, any greator or lesser number of cups may be brought into action either with or without breaking the circuit; likewise, all the cups in use may be charged (bringing new cups into use) without altering the number of cups in use.

Referring to the accompanying drawing i A and 13 represent two switches, made capable of revolving around a center common to both, and constructed or arranged the one to pass or play within or through the other, as clearly illustrated in fig. 3.

Thesmswitches are. insulated the one from the other, as by an insulator, b, arranged between the supports or bearings O and D, on or around which the switches are hung to rotate.

' Said switches carry rollers E and F, through which the connection with the cups is established or broken, by means of insulated conductors, G arranged to cross the paths of the rollers E and so that, on the switches being rotated, said rollers travel over and in contact with the conductors G.

These conductors G may be formed of radial plates, arranged, at equal distances apart, on or around a bed or table, II, and scparatcd by insulators I in the path of the circle traveled by the roller E of the switch A, when swinging or turning the latter, but

said conductors G have the spaces between them, left open in the path traveled by the roller F of the switch B, and said conductols and rollers are so proport-lobed that, while the switch A may be turned or adjusted to bring its roller E in contact; either with a conductor, G, or an intervening insulator, I,-

which establishes ,or breaks the r-annectiou oi the switch A with the cups of the battery, the switch B, in being turned, has its roller F always in contact either with one or two of the conductors G, thus securng a constant connection of such last-namcd switch with the cups of the battery.

t The object; of this arrangement will be hereinafter explained The conductors G are severally coin'ieote-d, by pins or screws 0 and suitable wires or continuations, with the cups of the battery, and the switch A connected, through its support 0, screw or pin (7, and wire (2, with the coupling J, that has attached to itthe end ot the wire by which she circuin is formed, while the other end of the circuit-wire is connected, through a coupling, J, wire 1', and screw or pin 9', with the, Switch B, through its support 1).

K K are locking-nuts, for securing the switches A and B at any particular position on the circuiobreaklog and closing table,

By the construction and arrangement of parts as described, the switches A and B maybe adj list/ed so that their rollers E and F establish connection, by both lying on a. single conductor, G, with only one cup of the battery, or with any number of cups, according to the number of conductors intervening between different conductors with which the rollers E and F are adjusted, to establish contact, and, accordingly as the switches are turned, to work the one within or over the other, in opposite directions or to opposite sides of each other, is the polarity reversed.

By the com pound switch, also, as herein described, any greater or lesser number of cups may be brought into action either with or without breaking the cirouib, accordingly as the switches A or B are moved for the purpose, the roller E of the switch A, by its alternate contact; with the conductors G and insulators I, breaking the circuin, while the roller 1 of tho switch 13, in never failing to keep up contactwith the conductors G, being in contact;- with two conductors when passing from one to another, allows of the numher of cops being changed, or of the polarity bcing reversed, without breaking the circuit.

By said compound switch, likewise, all the cups in use may be charged (bringing new cups into use) without changing the number oi cups in use.

What is here claimed, and desired to be secured by Letters Patent, is-- 1. A compound switch, composed of two switches,

A and 13, arranged to work independently of and insulnted. the one from the other, from or around a common center, ou-or over a. circuit-breaking and closing surface, substantially as specified.

2. 'ihe construction and arrangement, relatively to each other,ofi1he independent switches A and 13, whereby said switches, in working fl-Ol-Kl or around a common center, are free to play the one within or through the other, essentially as described.

3. The combination and arrangement of the con duotors G, which connect; with the cups, the inter-- veiling insulators Land the rollers E and F, of the eout-ect-snrfixces of the switches A and B, suhstnutiailly as and for the purpose specified.
